Abstract
The invention designs a novel endless chain feeding method. The novel endless chain feeding method is characterized in that a bar is straightened when passing through a straightening mechanism, the straightened bar continues to be conveyed forwards, after the bar collides with a limiting device at one end, conveying is stopped, a shearing mechanism works, the bar is shorn off (a feeding mechanism assisting in clamping the bar), after the shorn-off bar is pressed by a mould on a moving claw, an arched waist is formed, a landing edge is arranged on the movable claw (the position, outside the mould, of the bar is prevented from deforming), and the bar obtained after compression moulding is fed into a forming core film. The novel endless chain feeding method has the advantages that cracks prone to being generated in the chain welding process are reduced; pressing marks generated in the feeding and waist jacking process of a chain are reduced; fluctuation of the length of the chain is reduced, and the quality of the chain can be stabilized; the pressure of an ejector rod is reduced, and the service life of the core film can be prolonged.
Description
Technical field
The present invention relates to a kind of novel loop chain feeding method.
Background technology
In automation loop chain production process, when the wire diameter of material is lower than 18mm, mostly adopt wire rod as raw material.Need wire rod alignment during production, cut off, then by a pay-off, bar is sent in mould, machine-shaping.(see accompanying drawing one) loop chain is when adopting electric resistance welding, in order to increase the welding quality of chain, prevent rosin joint, the defects such as crackle, upsetting machine can be used during welding (to withstand the two ends of chain by external force, pressurization), under the pressure of upsetting machine, chain link welding position has the phenomenon of " shortening ".In order to the pitch of stable chain link, control the quality of chain, will according to the wire diameter of chain material when chain is knitted, the parameters such as the technique of elastic modelling quantity and welding, compensate welded chain " shortening " distance.
General feeding adopts the mechanism as accompanying drawing one: fixed claw is fixed on the below of feed mechanism, clamp by the movement of movable claw and discharge bar, but because the contact area of movable claw and fixed claw and bar is little, under the effect of chucking power, bar there will be distortion (bar that wire diameter is little is especially obvious), causes chain pitch instability.
When chain is shaping, within middle profile, (fiber near the part of core film can be compressed bar, in bar, beyond profile, the material of (away from core film) can be stretched, like this, due to the deflection (power needed for compression is greater than stretching) not of uniform size compressed and stretch, material can be caused to crack, even rupture.In order to address this problem, mostly can adopt and the middle part of chain is curved inwardly, become " arcuate waist ".Like this at chain link woollen yarn knitting, the fiber within middle profile has the position slippage of part to " bow star waist ", reduce the phenomenon of the crackle of the deflection generation not of uniform size of compression and stretching, and arc waist adopts push rod to pressurize mostly and the upper groove of core film produces.But the distortion of bar can be caused so not controlled, and under push rod pressure, impression can be caused on bar.Therefore a kind of new feeding method is urgently designed, to solve the problem.
Summary of the invention
The object of the invention is the problem that the chain link welding position solved in prior art when producing chain existing for weld upsetting machine has " shortening ", a kind of novel loop chain feeding method is provided.The present invention designs a kind of novel loop chain feeding method, it is characterized in that: bar is through aligning mechanism by bar alignment, and the bar after alignment continues to be fed forward, after knocking the stopping means being arranged on one end, conveying stops, shearing mechanism work, cuts off (the auxiliary clamping of feed mechanism) bar, bar after cutting off, after the mould on feeding claw is exerted pressure, formed " arc waist ", moving jaws is provided with scrap (bridge), bar after compressing, is admitted to forming core film.The crackle that advantage of the present invention easily occurs when being the reduction of chain woollen yarn knitting; Decrease the impression that chain produces when feeding and top waist; Reduce the fluctuation of bar length, be conducive to the stable of chain quality; Alleviate the pressure of push rod, be conducive to the service life extending core film.

Detailed description of the invention
A novel loop chain feeding method, is characterized in that: bar is through aligning mechanism by bar alignment, and the bar after alignment continues to be fed forward, after knocking the stopping means being arranged on one end, conveying stops, shearing mechanism work, cuts off (the auxiliary clamping of feed mechanism) bar, bar after cutting off, after the mould on feeding claw is exerted pressure, formed " arc waist ", moving jaws is provided with scrap (bridge), bar after compressing, is admitted to forming core film.
A kind of novel loop chain feeding process whole concept is: arrange mould by the clamping moving jaws of feed mechanism, utilize the chucking power of feed mechanism by " the arc waist " in the middle part of chain while feeding, compressing, and broaden moving jaws, two moving jaws are set.The course of work is as follows: bar through aligning mechanism by bar alignment, bar after alignment continues to be fed forward, after knocking the stopping means being arranged on one end, conveying stops, shearing mechanism work, bar is cut off (the auxiliary clamping of feed mechanism), bar after cutting off, after the mould on feeding claw is exerted pressure, is formed " arc waist ", moving jaws is provided with scrap (bridge), prevents the region deformation beyond the arc waist of bar like this.Bar after compressing, is admitted to forming core film, is arranged on the push rod action at middle part, withstands bar, and shaping mechanism is pressed into, chain ring forming.
During welding, shaping upsetting machine top, chain link two ends is pressed (withstanding the two ends of chain by external force, pressurization), then the welding of abutment joint place, under the pressure of upsetting machine, chain link welding position has the phenomenon of " shortening ".When upsetting machine carries out upset to chain link, and the mould on prior feeding claw exerts pressure " the arc waist " that formed, now the crooked position of chain link assembles internal stress under the external force condition on the inclined-plane of upsetting force and top, arc waist can produce slippage to weld with the material of crooked position, arc waist can decline a little, compensates welded chain " shortening " distance.The crackle easily occurred when decreasing chain woollen yarn knitting; And owing to creating in advance " arc waist ", decrease the impression that chain produces when feeding and top waist; Reduce the fluctuation of bar length, be conducive to the stable of chain quality; Alleviate the pressure of push rod, be conducive to the service life extending core film.
